7.8 Tone ID Switch
Fixed Tone ID or Variable Tone ID in Disc.
In the Fixed position, the tone of the audio signal from a target will
always be the same as the volume increases to indicate the target,
regardless of the object’s conductivity.
In the Variable position, the tone of audio signals
received will change to help identify the object that
has been detected. The lower an object’s
conductivity, the lower the pitch of the signal tone.
For example, the pitch of a piece of aluminium foil
will be lower than that of a gold coin.
The advantage of Variable tone target indication is that it allows a target
to be identified before recovering it from the ground.
7.9 Noise Cancel
When detecting in some areas, the threshold
stability may become chattery or unstable. This is
often caused by electricity or radio transmission and
most commonly of all, other detectors. The noise
cancel switch on the Sovereign Elite allows the
operator to select a different search band which will
often overcome this effect.
If detecting in pairs or a group, or when you experience instability due to
interference, switch to the other band to see if this overcomes the
problem.
The selection of Band 1 or Band 2 doesn’t affect the performance,
strength or sensitivity of the detector. Its only purpose is to stabilise and
lessen the effects of external interference.
Note: If there is no interference in the area, the operator is unlikely to
notice any difference between Band 1 and Band 2.
